This may have been posted some where but I couldn't find it. I'm new to the cub 185 and when I let my lever down my deck goes down but not my three point. I can help it down and when I raise the lever up the deck and the lift comes up fine. Am I doing it right? Does it supposed to go down when the deck does?

The Hyd's on the numbered series (154, 185, 184) are one way, meaning pressure up, but they require gravity to pull the implement down. If you have nothing connected, you'll have to help the cylinder down.

There should also be a valve on the tunnel that operates one cylinder at a time, either the belly lift or the rear lift.

You need to read the operators manual for your tractor. You can lock out either the mower deck or the 3 point hitch. Locking out the mower deck and unlocking out the 3 point and the 3 point operates. And viceversa. Most of the time the lock outs are manually controlled, remove lock out bar on 3-point and adjusting stop screws on mower deck lift apparatus.

On my 154 there are two hydraulic control valves on the tunnel cover. Lift one valve and the mower deck operates and 3-point locked out. Lift 2nd valve and the 3-point operates and the mower deck is lock out.

No. Reason we can't specifically answer the question is that we do not know how your Low-boy is set up.

Generally the tractors are set up to operate only the mower deck or the 3 point, but not both at the same time. Operating both systems at the same time, slows, really slows down, the action time of both systems.

Since you have no control valve on the tunnel, to operate the 3-point you will need to lock the deck into the elevated position and then remove the 3-point locking bar. Your operators manual will have photos and a description on how to perform each action.

I need to get a operators manual. I just got this tractor Friday. I've looked and I don't think it has a locking bar on the three point. I need to find a few more things for the three point. I have the cylinder and the rock shaft. I also have the bottom link plate and the plate the upper link fastens to. I need to find a manual so I can see how to lock the deck. Can a control valve be added?

You should be able to install a diverter valve so you can control them separately. I purchased a three point hitch for mine and had the shop that installed the hitch put a diverter valve in while they were doing the work. Lots of good help here on this site.

When the 3-point arms are added, the weight of the arms should be enough to cycle the cylinder down.Your tunnel is plumbed like my 184. Both cylinders are pressurized when actuating the hydraulics. The lowest weight implement lifts first (mower deck or 3-point).

The Tee shown in the tunnel picture is where a diverter valve is added. This is an expensive option for the tractor.
